For ages, anthropologists have puzzled over Neanderthal and human brains, since they were the same size. If each species had comparable brain power, why did humans dominate? A comparison of ...

Did the 12th century B.C.E. - a time when humans were forging great empires and developing new forms of written text - coincide with an evolutionary reduction in brain size? Think again, says a ...

The researchers link the size of the brain (in relation to the body size of each species) to intelligence, concluding that a large brain, which indicates – in comparison to different species of ...

Newborns' brains may look relatively smaller than those of other primate babies, but it's not because they're "underdeveloped" by comparison. When you purchase through links on our site, we may earn ...

Did the 12th century B.C.E. -- a time when humans were forging great empires and developing new forms of written text -- coincide with an evolutionary reduction in brain size? Think again, says a team ...

(CN) — Brain charts could allow doctors to compare the size and relative function of individual sections of a person’s brain with those of their peers across every age group, providing clinicians a ...

Behavior that we’d consider intelligent is oddly widespread in the animal kingdom. Animals with very different brains from ours—a species of octopus and various birds—engage with tools, to give just ...

Stegosaurus is one of those dinosaurs we all recognise straight away—big, slow, covered in plates, and dragging a spiky tail like it means business. But for decades, there’s been a running joke about ...

Researchers have examined the mass extinction of large animals over the past tens of thousands of years and found that extinct species had, on average, much smaller brains than species that survived.
